ABSTRACT:
Process for preparing trifluoroethyl sulfur compounds from thiolates and 1-chloro-2,2,2-trifluoroethane. The invention relates to the preparation of trifluoroethyl sulfur compounds of the formula RSCH.sub.2 CF.sub.3 by reacting 1-chloro-2,2,2-trifluoroethane CH.sub.2 Cl--CF.sub.3 in a polar aprotic solvent with salts of thiols of the formula RSH, where R can be an alkyl or aryl radical or a heterocyclic radical.
